Radon in Marathon Florida Water

Unhealthy Levels of Radon in the Water Supply of Marathon Florida Homes

Radon is a naturally occurring radioactive gas that can dissolve into groundwater and enter a home’s water system. While most people think of radon as an indoor air concern, it can be present in well water or other local supplies and then release into the air when you shower, do laundry, or run the dishwasher. In Marathon and elsewhere in Monroe County, homeowners often consider both water and air testing when addressing radon because moving water can send dissolved gas into the rooms where you and your family spend time.

Because radon has no taste, smell, or color, you can’t tell it’s in a glass or a plumbing line just by looking. The only dependable way to know your home’s condition is to test, since levels can differ block to block—even between neighboring properties in areas like Key Colony Beach or Grassy Key. If testing shows elevated radon in your water, a plan that fits your Marathon home’s plumbing and daily water use is the next step; treating water at the main entry point offers coverage for every faucet, shower, and appliance.
